    What is SLM 3D printing?

Are you a big fan of 3D printing? Whether yes or no, come and learn with me. I am going to show you what is SLM 3D printing.

Let's start from its name, SLM is the abbreviation of selective laser melting. From its name, we know that under the function of a laser, metal powder begins to melt and then solidify.

The basic principle of 3D printing is printed layer by layer and every item has its own shape.

To make that shape, the laser must be selectively not randomly.

Then how to make sure the printing is perfect?

First of all, unlike resin, metal powder is easy to oxidize. To ensure a good surface quality, we have to decrease the oxygen content to 0.01% and then input inert gas to avoid the chemical reaction。

Second, to make sure the printing accuracy. Adjusting the substrate to a horizontal state is fundamental. Any slight incline will influence the printing quality. 

Third, during the laser melting part. Smoke and some dust will produced. If not cleared timely, the printing quality will be influenced, too. And then it comes to the gas circulation filtration systems.

What kind of material can be used to print?

Currently, there are 12 printing materials that can be used in Kings SLM machines. 

They are: 

• Stainless Steel 17-4

• Stainless Steel 316L

• Stainless Steel 304

• Die steel 1.2709/18NI300

• Die steel CX

• Aluminum alloy AlSi10Mg

• Titanium Alloy TC4

• Cobalt-chromium alloy CoCrMo

• Copper alloy CuSn10

• Chrome Zirconium Copper CuCrZr

• Nickel-based superalloy 718

• Pure tantalum

The choices are quite wide, right? "What if I want to choose metal powder from a 3rd party?" That's OK. But during the warranty time using Kings is best.
